Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00124 | $0.01334 |
| Opus 5 | $0.00062 | $0.00667 |
| Sonnet 5 | $0.00025 | $0.00267 |
| Haiku 4.5 | $0.00012 | $0.00133 |
Grade A, and why
feature-guide scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill: feature-guide
Generates a structured feature card for any Claude capability — given a feature name or a description of what the user wants to accomplish. Covers: what it is, where it's available, how to use it, limitations, current status, and an applicability verdict.
Triggers
Russian: «что умеет Claude», «есть ли у Claude», «умеет ли Claude», «поддерживает ли Claude», «как включить фичу», «расскажи о фиче», «scout», «какие возможности у Claude», «как использовать», «feature scout» English: "what can Claude do", "does Claude have", "does Claude support", "how to enable", "Claude feature", "scout", "can Claude", "what features", "how to use", "feature scout", "Claude capabilities"
Language Detection
Determine the language of the user's request:
- Request in Russian → respond entirely in Russian
- Request in English → respond entirely in English
- Mixed request → default to Russian
Input
Required: a feature name OR a description of what the user wants to accomplish (free text, 1–2 sentences is enough)
Examples:
- «Есть ли у Claude память?»
- «Хочу чтобы Claude помнил мой контекст»
- "What is the Projects feature?"
- «Умеет ли Claude создавать файлы?»
- "Does Claude support voice?"
Output
One feature card per request, in structured format.
Instructions
Step 1 — Identify the request type
Classify the incoming request:
| Type | Signal | Action |
|---|---|---|
| Direct feature name | User names a specific feature: "Projects", "Memory", "Voice" | Proceed to Step 2 |
| Need description | User describes a goal: "I want Claude to remember things" | Identify the closest feature, ask one clarifying question |
| Ambiguous | Multiple features match | Offer up to 3 options, ask user to choose |
| Too general | "What can Claude do?" with no further context | Ask one question: "What specifically do you want to accomplish with Claude?" |
| AI comparison | Request mentions another AI product: ChatGPT, Gemini, Copilot, etc. | Decline: "This skill covers Claude's features only. Want to explore [feature from request]?" |
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

feature-guide is a skill published in the GitHub repository KirKruglov/claude-skills-kit (18 stars, last pushed 1mo ago), licensed MIT. It adds 124 tokens to every session and 1,334 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
